MAX98304
Mono 3.2W Class D Amplifier
General Description
The MAX98304 mono 3.2W Class D amplifier provides
Class AB audio performance with Class D efficiency.
This device offers five selectable gain settings (0dB,
3dB, 6dB, 9dB, and 12dB) set by a single gain-select
input (GAIN).
Active emissions-limiting, edge-rate, and overshoot con-
trol circuitry greatly reduces EMI. A filterless spread-
spectrum modulation scheme eliminates the need for
output filtering found in traditional Class D devices. These
features reduce application component count.
The IC's 0.95mA at 3.7V (1.2mA at 5V) quiescent current
extends battery life in portable applications.
The IC is available in a 9-bump (1.0mm x 1.0mm) WLP
with 0.3mm pitch that is specified over the extended
-40NC to +85NC temperature range.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.
